Given:
1.244 g sample of K20
Determine how many particles are found in the sample.
Molar Mass of K2O = 94.2 g
Solution:
In order to find the number of particles, we simply needed to apply the general conversion method.
= ( 1.244 g )( 6.023 x 10^23 / 94.2 g)
= 7.492612 x 10^23/94.2
=7.95 x 10^21 particles
Final answer:
=7.95 x 10^21 particles
